%headsepline, % Uncomment to get a line under the header
is not working anymore.
and how can I disable e.g. Chapter 5. Examples in the header.I just want on every "normal" page with exception of TOC, Nomenclature etc.) a line as header separator and just on the right side the page number.
BTW: You can the roman page number for TOC etc. be changed from e.g. ii to II (UPPERCASE)?
Many thanks for your help.
Cheers Michael
